Ace 4-1 header???
 

Just wondering if anyone has tried or heard of any power gains or results from the Ace 4-1 header i've been looking for headers to increase power gains for my brz but also want to be able to use the same headers for when I go FI. I spoke to a rep at ptuning (the turbo kit I am leaning towards) and they said the ace 4-2-1 header wouldn't work with their kit because of the overpipe combo. So I am debating on getting the 4-1 header since it doesn't seems I can use any overpipe. Any recommendations or experience with the Ace 4-1 header? PLS help LOL :bonk:

:search:

Official release of these new headers will be at the Taiwan's Auto Parts Exhibition April 6.

Anaconda 48mm for high horsepower (application and approval required. 1-2 month lead time).

Anaconda 42.7mm for anything under or around 400HP.

Headers will have package deals if using Ace OP. Headers also work with majority of other aftermarket OP's.

Will be available through Ace directly (www.aceheader.com), CSG (www.counterpacegarage.com) or Abbey Motorsports in UK (http://www.abbeymotorsport.co.uk/)

i personally think this header makes the most power

86Tony: At top rpms? Very probable. Shorter runners hint for that. But will it have biggest gains area under curve? Imho less probable. How often/long on average do you spend (even on track) at 6500-7500? Yes, it might be very track/gearing specific but my very wild guestimate is that "averaged" header like A250 may bring more average gains at average tracks one sees. And if daily driving is considered, then nothing will beat A350/CS400. That "most power" will mean nothing but bragging rights with dyno numbers, if you don't drive mostly at header's narrow optimized rpm range and actually use that more then for brief second before upshift. And that needs specific tracks and good skill-set imho. Not everybody is like CSG Mike, after all :)

We've found that the A/350 is the best overall header of the 150/250/350 group for overall driving.

moreso than the CS400? i pretty much live in the 3000-5000 RPM range. hardly am i shifting above 6000 for my DD purposes. (no track autox)

I haven't had enough experience to say with the CS400, but the A/350 is excellent.

You're getting a lot of love from CSG with two different perspectives! :happyanim:

CS400 is great for DD use, however, the overall powerband is the most generous and the best with the Type-A 350. :burnrubber:

Are you running with the Ace front pipe for DD? Worried about droning without a catted fp

Drone will be completely determined by your catback. With the stock catback there is zero drone. ZERO.

Lifes too short for stock :D

and he is right, catback will determine drone, so dont cheap out there either.

Perrin 2.5" resonated?

Any experience with a tomei type 80 catback with the ace 4-2-1 header type A 350 i've seem to make up my mind on which header but haven't heard what the header will sound like with the exhaust. Also any info on custom fabrications for turbo set up with ptuning turbo kit or the avo turbo kit?
